The Tools Menu

The Tools menu simply provides menu
access to all of the tools located on the upper area of the main
window. You will find the pointer (Modify), Magnify,
and Scroll tools. Remember, Shift with
Magnify or Scroll changes their behaviour. See
Section 24.4.1 for details. Next comes the four
standard shapes (Box, Ellipse, Polygon, and
Beziergon) followed by the five lines (Line, Arc,
Zigzagline, Polyline, and Bezierline). Finally
Image objects can be selected.

There is a significant reason for repeating the Tools here:
keyboard shortcuts can be easily assigned to each of the tools through
this menu. Simply move the mouse to highlight one of the menu items
and type the keystrokes you which to associate with that tool (e.g.,
Ctl+Alt+E for the Ellipse). The shortcut should appear on
the menu.
